4. RESTRICTED CASH

On December 29, 2012 and December 31, 2011, the Company had restricted cash of $329 and $46, respectively. Restricted cash reserves for customs and excise taxes in the U.K. operation were $48 and $46 at December 29, 2012, and December 31, 2011, respectively. The restricted amount was calculated as an estimate of two months of customs and excise taxes for items coming into the Company’s U.K. operations and is held with Lloyds TSB in the U.K. Restricted cash of $281 at December 29, 2012, represents the holdback of the purchase price associated with the acquisition of Seungwon on October 18, 2012.
